xcodebuild: error: 'mscore.xcodeproj' does not exist. make: *** [release] Error 66
I'm new to the MuseScore community and am interested in contributing to the project. Unfortunately, after spending a considerable amount of time, I am still unable to build the application on my machine. I cloned the GitHub repo and installed Qt (versions 5.4.2, 5.9.0, and 5.10.1, along with the tools). I've been able to confirm the version of Qt using "qmake -v" and cmake seems to be properly configured. With that being said, I cannot seem to go further than "make -f Makefile.osx revision". When I attempt to run "make -f Makefile.osx release", I am met with issues, notably Error 66 "'mscore.xcodeproj' does not exist.".
Any advice would be much appreciated.
